disk-cleaner
by gccszs
"High-performance cross-platform disk space monitoring, analysis, and cleaning toolkit with v2.0 optimization enhancements. Use when Claude needs to: (1) Analyze disk space usage and identify large files/directories consuming space, (2) Clean temporary files, caches, logs, and other junk files safely, (3) Monitor disk usage with configurable warning/critical thresholds, (4) Generate detailed reports on disk health and cleanup recommendations. Features advanced optimization: 3-5x faster scanning with os.scandir(), concurrent multi-threaded I/O, intelligent sampling for large directories, memory-adaptive processing, and cross-platform compatibility (Windows/macOS/Linux). Specializes in Windows C drive cleanup while maintaining full compatibility with Unix systems. Provides interactive CLI, automated scripts, detailed reporting modes, and comprehensive test coverage (244 tests). All operations prioritize safety with built-in protection for system files."
hierarchical-matching-systems
by petekp
Expertise in architecting, implementing, reviewing, and debugging hierarchical matching systems. Use when working with: (1) Two-sided matching (Gale-Shapley, hospital-resident, student-school), (2) Assignment/optimization problems (Hungarian algorithm, bipartite matching), (3) Multi-level hierarchy matching (org charts, taxonomies, nested categories), (4) Entity resolution and record linkage across hierarchies. Triggers: debugging match quality issues, reviewing matching algorithms, translating business requirements into constraints, validating match correctness, architecting new matching systems, fixing unstable matches, resolving constraint violations, diagnosing preference misalignment.
personality-profiler
by petekp
Generate rich personality profiles from social media data exports (Twitter/X, LinkedIn, Instagram). Use when a user wants to analyze their social media presence, create a personality profile for AI personalization, understand their communication patterns, or extract insights from their digital footprint. Triggers on requests like "analyze my Twitter data", "create a personality profile", "what can you learn about me from my posts", "personalize an AI for me", or when users provide social media export files.
cognitive-foundations
by petekp
Apply cognitive science and HCI research to design decisions. Use when you need the scientific 'why' behind usability, explaining user behavior, understanding perception/memory/attention limits, evaluating cognitive load, assessing mental model alignment, predicting performance with Fitts's/Hick's Law, or grounding interface decisions in research rather than opinion.
process-hunter
by petekp
CAVEMAN HUNT BAD PROCESS! Me find greedy creature eating fire and rocks. Me bonk them good. Use when tribe say "kill processes", "clean up servers", "save battery", "find resource hogs", "bonk next.js", or "hunt processes". Me bonk known bad creature automatic. Me ask before bonk mystery creature.
advanced-rendering
by uw-ssec
Master high-performance rendering for large datasets with Datashader. Use this skill when working with datasets exceeding 100M+ points, optimizing visualization performance, or implementing efficient rendering strategies with rasterization and colormapping techniques.
dspy-miprov2-optimizer
by OmidZamani
This skill should be used when the user asks to "optimize a DSPy program", "use MIPROv2", "tune instructions and demos", "get best DSPy performance", "run Bayesian optimization", mentions "state-of-the-art DSPy optimizer", "joint instruction tuning", or needs maximum performance from a DSPy program with substantial training data (200+ examples).
performance-optimization
by ynulihao
Apply systematic performance optimization techniques when writing or reviewing code. Use when optimizing hot paths, reducing latency, improving throughput, fixing performance regressions, or when the user mentions performance, optimization, speed, latency, throughput, profiling, or benchmarking.
cdr3clustering
by pwwang
Cluster TCR/BCR clones by CDR3 sequences using GIANA or ClusTCR (both Faiss-based). Adds CDR3_Cluster column to metadata for clonotype analysis.
modulescorecalculator
by pwwang
Configuration skill for immunopipe process
metabolicexpimputation
by pwwang
Imputes missing/dropout values in scRNA-seq expression data to improve metabolic pathway analysis. This process handles sparsity common in single-cell RNA sequencing data by filling in zero values using advanced imputation methods (ALRA, scImpute, or MAGIC). The imputed data provides more accurate metabolic pathway activity calculations and feature selection in downstream analysis.
submit
by kazukinagata
This skill should be used when the user is ready to submit their tax return, needs a final review checklist, wants to know how to submit (e-Tax, mail, or in-person), or asks about common mistakes before submission. Trigger phrases include: "提出準備", "提出方法", "e-Taxで提出", "チェックリスト", "申告書の確認", "提出前の確認", "郵送で提出", "税務署に持っていく", "提出期限".
brand-voice-extractor
by BrianRWagner
"Extract or build a distinct brand voice profile that AI agents can use to produce on-brand content every time. Two modes: Extract (analyze content you're proud of) or Build (construct a voice from scratch). Outputs a complete voice profile with personality traits, tone spectrum, vocabulary guide, rhythm patterns, and example phrases. Use this before any content creation skill for consistent, human-sounding output."
plan-my-day
by BrianRWagner
Generate an energy-optimized, time-blocked daily plan based on circadian rhythm research and GTD principles
marketing-principles
by BrianRWagner
Apply timeless marketing and business principles to any problem. Use when someone needs strategic thinking, wants to evaluate a marketing decision, needs a framework for a tough choice, or mentions "first principles," "should I do X," "what would work here," or wants to think through a marketing problem systematically.
